My dad runs a medical practice that has been using the same iMacs and Powerbooks (and one PowerMac) since they were purchased in ~2002. Anyway, they were in mint condition, since they were kept safely in the clinic. I went there this morning and noticed that all the computers had been replaced with new Macs (yay!). My dad had given the other computers to my sister to distribute to any of her friends that needed computers. Upon checking up with my sister, apparently she took them to the dump because they wouldn't run modern software. So she assumed that they were useless. Urg! Such a waste. I'm quite sure that I could have sold those.
